Title: Production of ion-selective glass
Inventor: OKADA TAKAO
IPC: C03B8/04
Filed: 1983-11-14
Abstract: PURPOSE:To obtain a high-purity glass having excellent ion selectivity and suitable as a sensor, etc. at a low cost, by using a plurality of raw materials for the forming of glass having selective sensitivity to ions, and producing the glass by the vapor-phase growth process. CONSTITUTION:A plurality of raw materials (e.g. SiCl4, AlCl3 and Na) for forming a glass having selective sensitivity to ions, are bubbled with respective bubblers 25, 26 and 27, atomized or vaporized with a carrier gas such as argon, and introduced into the quartz glass tube 29 together with oxygen. The quartz glass tube 29 is scanned longitudinally with the electrical furnace 30 to effect the reaction of the raw materials introduced into the quartz glass tube 29. The reaction product of SiO2, Al2O3, Na2O, etc. are grown from the vapor phase to the inner wall of the quartz glass tube by this process. The quartz glass tube 29 is then collapsed and solidified by melting with heat to obtain the preform of an ion-selective glass.

Title: Welding state judging method with appearance inspection
Inventor: SHIRASAWA MITSURU
IPC: H04N7/18
Filed: 1991-08-27
Abstract: PURPOSE:To execute an image processing not containing a processing concerning the height information of the surface of an object to be inspected while simplifying the configuration of a light source to iradiate the surface of the object to be inspected. CONSTITUTION:An inspecting area is set at a point welded by laser welding (step S1).

Title: Memory circuit
Inventor: CHIBA KAZUKI
IPC: G11C7/00
Filed: 1988-08-29
Abstract: PURPOSE:To reduce the time required for readout by selecting one of two memory cell arrays corresponding to two address latch circuits whose switching depends on the least significant bit of the address and giving an output. CONSTITUTION:Address latch circuits 1a, 1b are so controlled that they reach the input state when the least significant bit of the address is 0, 1 by a control circuit 4 and they hold the address inputted precedingly when the least significant bit of the address is 1, 0. The address inputted to the address latch circuits 1a, 1b is decoded respectively by decoders 2a, 2b to select a memory cell in the memory cell arrays 3a, 3b respectively. In the case of readout, either the data of the memory cell array 3a or 3b is selected and read externally via an input/output buffer 6. Thus, while the data in the memory cell is being read, the address inputted later is decoded and the time required for readout is reduced.

Title: Intake exhaust valve driving apparatus for internal- combustion engine
Inventor: HARA SEINOSUKE
IPC: F01L1/24
Filed: 1982-12-07
Abstract: PURPOSE:To permit the timing or the lift of an intake exhaust valve to be varied by a small driving force, by varying the tilt of a lever for supporting the swing fulcrum of a locker arm, by a hydraulic actuator which extends and contracts. CONSTITUTION:An intake/exhaust valve 12 is opened and closed by a cam 11 through a locker arm 17. The back surface of said locker arm 17 contacts with a lever 20, and the position of the swing fulcrum of the locker arm 17 shifts in accordance with the tilt angle of the lever 20, and the opening and closing timing or the lift of the intake/exhaust valve 12 is varied in accordance with the above-described shift. The tilt angle of the lever 20 is adjusted by a hydraulic actuator 25. Therefore, the tilt angle of the lever can be controlled for each valve, by utilizing a suspension time in which the intake/exhaust valve is not lifted, and the controlling driving force is reduced, and the necessity of using a large actuator is obviated.

Abstract: PURPOSE:To reduce a noise contained in a chrominance signal in a dark picture, and to obtain the picture easy to see in visibility by changing the saturation of a chrominance signal according to the size of a luminance signal. CONSTITUTION:In a synchronizing separation circuit 7, only a horizontal synchronizing signal part of a regenerative luminance signal is extracted, and by delaying it by definite time by a delay circuit 8, a burst gate pulse (c) is generated, and this burst gate pulse (c) is inputted to a CGC (chrominance signal saturation control) circuit 9. The CGC circuit 9 operates during a period (t) when the burst gate pulse (c) is Hi-level, and it does not operate at the time of Lo- level. Accordingly, the amplitude of color burst signal B among the chrominance signal sent to the CGC circuit 9 and shown in a figure (d) is kept constant, and only the chrominance signal part C is changed by the amplitude of the luminance signal, and the color saturation is changed as shown in a figure (e) Thus, the noise of the chrominance signal at the time of the low level of the luminance signal can be reduced, and the picture easy to see can be obtained.

Abstract: PURPOSE:To improve the stability and reliability as well as a.c. loss by coating the surface of superconducting wire with amorphos alloy. CONSTITUTION:A superconducting wire to be used at a very low temp. is provided which is coated with amorphos alloy on its surface. Amorphos alloy has the strong joining strength (95kg/mm<2>) with a base material as well as excellent friction resistance (wear coefficient 0.1 or less), wear resistance and corrosion resistance characteristics, and radiation damage resistance, thereby having a strong resistance to repeated rubbing of the mutual thermally treated conductive wires and a characteristic hard to be peeled off. When applied to a heat treated wire the same effect can be obtained by the use of amorphous alloy of noncrystalline type under the conditions, and in the aspect of assuring a.c. loss characteristic the reliability is improved remarkably. Though the major disturbance and the like on the superconducting wire involved with the safety result from the frictional heat generation caused by movement and the like of superconducting wire, the frictional heat generation can be reduced to the minimum by the use of amorphos alloy with a very small frictional coefficient and the stability is also improved.
